set picking select

is there a Jmol equivalent of 'set picking select' yet? IOW, a mode
in which clicking an atom with the mouse adds that atom to the
selected set.

Chime has several powerful modifications to this mode:

1. set picking select atom|bond|chain|residue

2. three different sub-modes: a click adds to the current selection,
replaces the current selection, or removes the clicked atom from the
selection.

thanks!
